CONCRETE BUILDING CONSTRUCTION.

Application-filed March 20, 1922. Serial No. 545,383.

T 0 all whom it may concern:

Be it known that I, ARTHUR H. OLMsTED, citizen of the United States, residing at Rye, in the State of New York, have invented certain new and useful Improvements in Concrete Building Construction, of which the following is a. specification.

This invention has relation to building construction and has for an object to provide a new methodand means for constructing walls, floors or other parts of a build ing through the medium of what I term precast units, which are placed in position in spaced relation so that plastic material may be flowed therebetween to unite with the precast units and form a monolithic structure.

Another object of the invention is to provide a novel form of stud which may be constructed of any desired material and adapted to support mold boards at either side so that concrete or the like may be poured between the studs to form a wall structure or the like, the studs being so formed as to permit the concrete mixture to flow through and around them to create a monolithic structure. 1

Another object of the invention is to provide a stud, perferably of concrete and having openings therethrough and marginal recesses, reinforcing tie rods to support vertical and lateral strain, and a novel means associated with the tie rods upon which mold boards may be supported to form a monolithic wall structure.

In addition to the foregoing this invention comprehends improvements in the details of construction and arrangement on parts to be hereinafter described and par- -ticula'rly set forth in the appended claims.

In the accompanying drawings in which similar and corresponding parts are designated by the same characters of reference throughout the several views in which they appear.

Figure 1 is a fragmentary, perspective view, partially broken away of a wall showing the application of my invention.

Figure 2 is a view taken-substantially on the line 2-2 of Figure 1. v 4 With reference to the drawings, 10 indicates generally a precast unit or stud. This may be constructed of concrete, or any composition such as wood, metal, fibrous material desired or found suitable for the purpose. It is relatively long and more or less oblong in cross section, although any dimensions may be employed upon which to base its construction, aswill be readily apparent upon further description." The stud is formed with one or more transverse openings 11 and each endof the stud is formed with a recess 12. One edge of the stud is formed with recesses 13 whichin the present instances are located at points between the openings 11. Longitudinal reinforcing rods 14 extend throughout the length of the stud, are embedded therein and run along the walls of the openings ll but within the material of the stud. I also provide along both edges of the stud a plurality of socket members 15 which are embedded in the stud and which may be set in from the face of the stud by washers 16, said washers lying flush with the surface of the stud, and may be removed after the stud has set. The

opposite end of the socket is formed with I will successfully take up all strain applied to the stud from any direction whatsoever. Each socket member is tapped'and threaded as shown.

In building a wall or the like the studs 10 are arranged in spaced relation at any desired distances apart according to the circunligtances and to properly support the mo Horizontal reinforcing rods 22 may be in- I serted through the horizontally aligned openings 11 and the horizontally aligned recesses 13 of the studs. The concrete or other plastic material is now poured between the recesses 13 as well as the recesses 12, and by uniting with the surface of the material of the studs creates with said studs'a monolithic wall structure. The studs, be they molds filling up the spaces between the H studs, flowing through the openings 11 and of concrete, wood or any other material will I remain in position and constitute'part of the wall structure. The mold boards are then removed and the surface of the wall finished in any manner desired.

It will be obvious that I may form studs without the openings 11 and only employ marginal recesses. A stud of this character may be utilized for constructing thin partitions since the studs may be made much narrower. Hence, I do not wish to limit myself to the exact formation of the stud as herein illustrated and described but to construct a stud of any desired dimensions, with or without openings or recesses, rei11- forcement and in fact any possible variation within the spirit of the invention. Special attention is directed to the fact that the formation of an uninterrupted joint in the surface of the wall between the sides of the stud and the masses of plastic material at either side thereof is prevented by the provision of the recesses 13. In this manner surface cracks in the wall will be positively prevented. It will be observed that the studs may be used as vertical supporting pillars for a building construction during or after the erection of the building. A wall of unequal thickness may be constructed with the use of these precast units or'studs and also dead air spaces may be formed in the wall by the use of furring strips or the like. Also, a skeleton wall may be constructed of these studs by binding the top and bottom ends together in situ in any manner desired, the structure of the studs permitting such use without the necessity of a plastic filling between thestuds. Lathing or expanded metal may be applied directly to the studs or to furring strips attached thereto and in pouring the wall material said material mayfiow into the expanded metal forminga rigid support. Auxiliary devices such as blocks, supports, builders hardware or the like may be precast with the studs thus forming special studs for use around door and window openings or in any other conceivable situation. Special studs of great strength but embodying the principles of my invention ,may be used as supporting pillars and subsequently become a part of the wall structure. It will be also observed that the studs may be used either permanently or temporarily to support the floor while the walls are being poured and until such time as the concrete of the wall is sufficiently hardened to support the floor. This may ,be accomplished by letting the floor members rest on the horizontal aligning beams or by bolting supports to the socket members 15. It will thus be seen that I have provided a novel method of building construction which will lend itself to any kind of design, height of building, thickness of walls and which will ensure a thoroughly fire proof construction. A great saving of time and labor can be secured because of the fact that the studs may be manufactured elsewhere and shipped to the building site where they may be quickly assembled by unskilled labor. Other uses and advantages will readily occur to those familiar with the art to which this invention appertains.

.1 have illustrated in Figure 1 an arrangement in which my precast studs are associated with floor supporting members, in this instance indicated at These are precast floor joists or beams and are each provided at one or both ends with notches 26 which are formed in the edge. The joists are'intended to rest edgewise upon the upper ends of the studs 10. An aligning member 27 is employed and inserted through the horizontally aligned end recesses 12 described above. This member may be in the form of a precast beam, angle iron, wooden plank or any material found suitable. It will be noted that the edge of the aligning member projects above the upper end of the stud so as to enter the notches 26. A rigid connection is thus provided which will prevent displacement of the members of the structure while the balance of the wall or structure is being poured.

While I have illustrated and described my invention with some degree of particularity, I realize that in practice various alterations therein may be made. I therefore reserve the right and privilege of changing the form of'the details of construction or otherwise altering the arrangement of the correlated parts without departing from the spirit of the invention or the scope of the appended claims.

Having thus described my invention what I claim as new and desire to secure by United States Letters Patent is 1. A building unit comprising an el0ngated member, a plurality of socket members imbedded in the member and having their ends exposed at the edge of the elongated member, said socket members being internally threaded, and tie rods connecting the inner ends of adjacent socket members.

2. A building unit comprising an elongated member, a plurality of socket members imbedded in both edges of said member, an eyelet formed on the inner end of each socket member, tie rods connecting the inner ends of opposed and adjacent socket members, and longitudinal reinforcing rods running through the eyelets of the socketmembers at each side of the elongated member, said socket members being internally threaded.

3. A building unit comprising an elongated slab having a plurality of elongated openings arranged longitudinally and recesses in the edges, one recess between an adjacent pair of openings, and end recesses, socket members imbedded in the edges of the member in opposed pairs and located between each opening and an adjacent recess, an eyelet formed on the inner end of each socket member, tie rods connecting the eyelets of opposed socket members, and longitudinal reinforcing rods running through the longitudinally aligned eyelets.

4. A Wall construction comprising vertical perforated and recessed members, socket members imbedded in the edges of the members, tie rods connecting the inner ends of the socket members, vertical reinforcing rods extending through the members, horizontal rods extending through the perforations and recesses, and a filling of plastic material between the members and extending through the perforations and recesses to form a monolithic Wall structure.

5. In combination, vertical studs having end recesses, an aligning member in said recesses projecting above the ends of the studs, and horizontal members resting upon the ends of said studs and having notches to re- 20 ceive the edge of the aligning member.

In testimony whereof I aifix my signature.
